Be it known thlt I, L'o'iis MARCEL GA- Biar Lorena, einem of 'are Republic of Freilassung 'ai` i1 eee nonoui-S, Preis, France,-l have inyented ertain new and ilse'- y irigibl'e Lights', of Whichfthe following is ay specification, reference being had therein to the accompanyine'drai/ving. jv A, h's inventionhasiioi' its object certain improvements in the Y iyotted or jointed head lamp 'or` searchhght carrier which orins the subject matter of my U. S. Letters Patent No. 1,062,833. This head lamp isinount'e'd so as to he able to he operated frein a distance,v and it enables the beam of light to he projected upward or downward as .Well as to right or. left.

Y 'n lthe patent above,named an arrangen'ient has been describedv forcau'sing the lanip to oscillat'e on its trunnio'ns and abont the' axis ofthe supporting forkj 'comprising toothed pinions .mounted o'n. one of the dti'uni'on's ofthe'lampyand on the rod of the supporting fork, the said inions gearing` with' chains which are 4'coirtiinled by, cables surrounded with flexible slieaths and con nected with the `-ends, 'o cruciform :arms mounted after the Vmanner of a Cardan joint and operated by a singlelever fixed at the intersection of the arms. This arrangement of crucioi'm ai'n'is foroper'ating the cableshas the 'disadvantage of. not permitting the 'calol'e's t'o iave a uniform tension while being operated, and the headlight responds less perfectly to the 'increments which it is desired to give it. I

According to the present invention the cruciiiorin arins are replaced by a combination oi: pulleys which yield the saine result, while however insuring a uniform tension of the cables. Further a solid and compact arrangement is obtained which enables the controlling member to he easily arranged within reach :of the driver when the head lamp is employed for motor cars.

Now referring to the accompanying drawings: Figurel isa partial front View of the head light, its supporting` fork being shown in section; Fig. 9.' is a side View of the head light with the lower part of its support in section; Fig. 3 is a plan View of the means for giving the head light a rotation ahout its vertical axis; Fig. fr is n View in perspective of the apparatus for through the interior of the erin o2 t @immens Lire-He".

Li. end of the stein ,-l a pinicj lwhich `f-i'ears 'witha chain j. te the ends of which two cables lei-*l5 are attached which connect with the voperating apparatus shoivn in Figs. fi and 5. The whole mechanis'ni of this apparatus' is held suspended beneath a suit-able support by a rod 16 of square section vthreaded at its` end in order to receive a nut. On this square rod a sleeve 17 which is cylindrical externally is fitted and is secured by the nut on the i `d. This sleye has tivo arrnsl which forni fork and hold between nthem a pulley which revolves on an axis 20. The sappen"- ing sleeve i7 ci this pulley heinfY iiXed. 'l s pulley 'can i eine in the s; e vertical plane. i

The external cylindrical part of the sleeve lserves a pivot to a concentric sleeve 21, the tiyo arms of v`iich carry a horizontal alley 2:2 oit the saine diameter as the pilliey S), out as tl esc tno li o al'lioughheing oi. the saaie hair musi., he independent .C lie eccentric and other. To this end the pulley 22 is slotted the arm of the pulley 'lil to `When the ;l the two parts of the mounting' is compl. c

A 1 irc i "together and pulley 22 may then l held if neces: inner side of o r simultaneously in order to produce dis-- placements of the cables. the resultant "of which will the desired position to the head l this purpose the handle 1. plate screwed. on the at in order to allow gee wir

' of the handle cause the rotation in a horizontal plane of the pulley 22. For this purpose this pulley has in addition to these supporting arms a semicircular sector 27 which has a slot 28 into which the rod of the handle 24 fits and which acts a guide piece for the latter. It is evident that in this way thc pulley 22 will follow the handle in all its lateral displacements and in order to allow of these lateral displacements of the .handle th puuey 19 is Slotted at e9 between the arms of the joint of the handle 24. When the handle is dis laced obliquely it simultaneously controls tie two pulleys and the resultant of the displacements of the cables will give the head light the desired inclination.

The semi-circular sector 27 along the slot 28 may be provided 'with notches While the handle has a stud yieldingly mounted which engages the correspondingr notch in such a manner that the handle remains fixed in each position. The pulley 22 rotating in a horizontal plane may be fixed in position by a screw `37.

In orderpthat the operating cables may always remain taut, the are surrounded with sheaths formed vo helically lwound metal wires. The sheaths which surround the cables 9 and 10 abut on the one: hand against .a plate 30 placed in the upper4 art 0 4the furka-little below the pinion 6. hey pass through an oblong aperture 31 formed 1n the late 32 and their other end against a regu ating nut. The cables` 14--15 are also surrounded with sheaths. These latter `abut on the one hand" against 'a regulating nut and on the other -hand against thel late 32. Incase the distance betw en the ead light. and theo erating lever necessitates a second series o sheaths for the tension of the cables, the latter may'bekept'taut by a common regulating arrangement or even each ofthe latter may be provided with a separate regulating nut.

l Inthe description the means which have appeared to be the most .advantageous for putting the invention effectively into practice have been described, but itl will be evident that the details of construction arey adapted to be modified and that the invention is based on the application of the characteristic arrangements which have been indicated, while these arrangements may be employed separately or in combination.

' Having now partcularlydescribed and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

1. 'A pivoted su portingV fork an'd a light pi'votally mounte thereon; in combination with two pulleys intersecting each other and mounted to revolve on axes at right angles to eachother, a handle engaging both of said pulleys and adapted to control either or both at will, and separate cables con nected to said pulleys and to said fork and pivoted light respectively, whereby movements of saidl pulleys arey transmitted to said 1ight,'substantially as described.

2. In a means for transmittingl movements to alight mounted so as to be tiltable on two axes, a fi ed mounting, a revoluble pulley lcarried t ereby, a sleeve revolubly carried on said fixed mounting, depending arms on said sleeve, a second pulley carried by said arms having a rim intersecting said first lnamed pulley, a handle fixed to the hub of said first named pulley, means fixed to said second pulley engaging' said handle, and cables, attached to and extending from said pulleys respectively to said light and operatively connected to said light, substantially as described.

@In witness whereofl have hereunto set my hand in the presence of two witnesses.
